We're dividing 18203888 by 457 
Our goal is to divide 18203888 by 457.

Going ahead to step 1:
When dividing 1 by 457, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 457

Advancing to step 2:
The number 457 fits into 18 0 times, leaving a remainder of 18.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Fetch the next digit (2) from the dividend, attach it to 18 and continue: 182 / 457

Step 3:
When dividing 182 by 457, we get 0 with a remainder of 182.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 182 and we're left with 182.
Fetch the next digit (0) from the dividend, attach it to 182 and continue: 1820 / 457

Moving on to step 4:
457 goes into 1820 3 times with a remainder of 449.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 1371 from 1820 and we're left with 449.
Include the next digit (3) from the dividend after 449, then repeat: 4493 / 457

Advancing to step 5:
457 goes into 4493 9 times with a remainder of 380.
The next digit of our result is 9. 
Result so far: 39.0
If we take 4113 away from 4493, we end up with 380.
Include the next digit (8) from the dividend after 380, then repeat: 3808 / 457

Going ahead to step 6:
457 can be fit into 3808 8 times, resulting in a remainder of 152.
The number 8 becomes the next digit in our result. 
Result so far: 398.0
Subtract 3656 from 3808 to get 152.
Bring next digit (8) of the dividend behind the 152 and repeat the process: 1528 / 457

Advancing to step 7:
When dividing 1528 by 457, we get 3 with a remainder of 157.
Write down 3 as next digit of the result. 
Result so far: 3983.0
Subtracting 1371 from 1528 leaves us with 157.
Fetch the next digit (8) from the dividend, attach it to 157 and continue: 1578 / 457

Advancing to step 8:
When dividing 1578 by 457, we get 3 with a remainder of 207.
Record the quotient 3 as the next digit in the result. 
Result so far: 39833.0
If we take 1371 away from 1578, we end up with 207.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2070, and continue the process.

Step 9:
2070 divided by 457 is 4 with a remainder of 242.
Put 4 as the next digit of the answer. 
Result so far: 39833.4
Subtracting 1828 from 2070 leaves us with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 10:
457 can be fit into 2420 5 times, resulting in a remainder of 135.
The next digit of our result is 5. 
Result so far: 39833.45
Subtract 2285 from 2420 to get 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Moving on to step 11:
457 can be fit into 1350 2 times, resulting in a remainder of 436.
Write down 2 as next digit of the result. 
Result so far: 39833.452
If we take 914 away from 1350, we end up with 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4360, and continue the process.

On to step 12:
4360 divided by 457 is 9 with a remainder of 247.
Record the quotient 9 as the next digit in the result. 
Result so far: 39833.4529
Deduct 4113 from 4360 and we're left with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

Advancing to step 13:
If we divide 2470 by 457, we get 5 and a remainder of 185.
Put 5 as the next digit of the answer. 
Result so far: 39833.45295
Subtracting 2285 from 2470 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 14:
If we divide 1850 by 457, we get 4 and a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 39833.452954
If we subtract 1828 from 1850, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 15:
If we divide 220 by 457, we get 0 and a remainder of 220.
Put 0 as the next digit of the answer. 
Result so far: 39833.452954
If we take 0 away from 220, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 16:
When dividing 2200 by 457, we get 4 with a remainder of 372.
The next digit of our result is 4. 
Result so far: 39833.45295404
Subtracting 1828 from 2200 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

After the division, we end up with 39833.45295404 and a remainder of 3.72e-07.
